Abstract

<B><MU>MéTODO PARA VARRER UMA IMAGEM<MV><D> Um scanner de leitura única contendo um sistema trilinear, uma fonte de luz branca, filtros das três cores primárias e uma fonte separada de luz infravermelha é usada em vários métodos de remoção de defeitos baseado nos instrumentos a partir de uma imagem de película varrida. O método gera um canal infravermelho além dos canais visíveis comuns cobrindo as linhas paralelas dos sensores no sistema trilinear respectivamente com um filtro vermelho, verde, e azul para criar os três canais coloridos. Normalmente, cada um dos três filtros coloridos também passa luz infravermelha, que é removida por filtros externos aos sensores. Numa modalidade específica, intersticial em tempo entre duas varreduras de luz visível, o sensor é exposto à luz infravermelha para uma simples varredura. Como o sistema trilinear varre a imagem transversalmente em sincronismo de tempo e espaço com as luzes expostas, pelo menos dois canais visíveis e um canal infravermelho são gerados.<B> <MU> METHOD FOR SCANNING AN IMAGE <MV> <D> A single-reading scanner containing a trilinear system, a white light source, filters of the three primary colors and a separate source of infrared light is used in several methods instrument-based defect removal from a scanned film image. The method generates an infrared channel in addition to the common visible channels covering the parallel lines of the sensors in the trilinear system respectively with a red, green, and blue filter to create the three colored channels. Typically, each of the three colored filters also passes infrared light, which is removed by filters external to the sensors. In a specific modality, interstitial in time between two scans of visible light, the sensor is exposed to infrared light for a simple scan. As the trilinear system scans the image transversely in synchronization of time and space with the exposed lights, at least two visible channels and an infrared channel are generated.
